wheel comprises a central cylindrical or tion 113that is closed at theupper end, w 'ch fits over the inner end of the shaft 11, and radial blades orpartitions 1 1 extend from the p on 3 to Ou pheryv f t e Wh elie u. A cylinderv surrounds theiwheel and con-Q tacts with the outer ends of the radial blades or partitions 14;, this cylinder being prefer ably slightly larger than the lower end 4 of r the ring 4, a Division orvpartition plates 16: so thatoperate as guide plates are located between alternate partitions 14;, each oneextending from the upper end of the cylinder 13 downwardly and outwardly to positions in termediate the center and the cireumference" 0,5 ofthe wheel, so that the lower ends of these plates 16 will be approximately inline with the circular rim of the inlet 5 to the branch conduit 2. Other division on partition plates 17 that alsooperate as guide plates e1 ternate with the plates 16 between the radial blad 14 and extend r m evuppe r cu r periphery of the wheel downwardly and in:

wardly so that their lower ends are on the circumference of the same circle as the lower (5 ends, of theplatesl 16. Clearly the guide plates 16 and 17arenon-radial. Itwillthus" be seen that there aretwo sets of passage- Ways hr gh the e 1 n a a ia ime; tion, the entries to each of the passageways being .of substantially the same shape with one setof the passageways having one side sloping outwardly toward the circumference of the wheel and the other set having one side sloping inwardlytoward the center of the wheel so that the outlets of one set of pas: Sa y e e ou s f termediate circle and the outlets of all of the other passageways are inside of the same circle In this way if the material arrives at the wheel 9 throughthe conduit 1 Withthefsolids concentrated along certain lines, the inlets to the passageways which are carried across the entire cross sectional area of thelower end of the ring 4: in the shaft 11 are revolved and. 06 will catch material from all portions of the conduit 1 and mix the same so thatthejmixe ture carried off the branch conduits 2 and 3 will be substantially homogeneous.

The conduit l which is described alogwe, t

forms a casing for the distributor, and above the distributor forms an inlet therefor. The inlet 5 to the branch conduit 8 and the annular space 7 comprise a plurality of outlets from the casing. The radial blades 14; ex tend from the inlet to the outlets. It will be evident that the division or partition plates 16 form cone surfaces extending from the upper part of the central cylindrical portion 13. downwardly and outwardly of the distributor. The division or partition plates 17 also form cone surfaces which extend downwardly and inwardly of the distributor. The partitions 14 extend outward ly from these cone surfaces. Obviously, other arrangements of a similar character mightbe substituted for that which is here specifically described.

The'wheel is provided with a bearing mem ber 20 and a roller bearing 21 is provided be-' tween this member and the bearing 9 on the spider 8.

j In the modification shown in Figs. 6 and 7 the shaft 11 and driving .pulley 12 are dispensed with and the radially disposed plates 14 are curved along their lower portions circumfe-rentially so that the material passing, through the conduit 1 will impinge upon the curved surfaces and impart rotary motion to the wheel and thus cause the material to'be mixed as it passes into the branch conduits.
